Heza Posted July 31, 2003 Report Posted July 31, 2003 so i had my exhaust done last week and then i went home only to notice a rattling noise in front of my catalytic converter at certain RPMs. annoyed the hell out of me. went back to the exhaust place and they cut the cat off and the cat made no rattles. hit the down pipe and there it was. i looked inside and saw there was some sort of internal heat shield or some shit that rattled. what the hell is that? can anyone tell me? well, we welded it to the downpipe and no more rattling.

cmo1234 Posted July 31, 2003 Report Posted July 31, 2003 Yea mine rattles too, but i figured it was the cat cause its never been replaced in 155k mi, so when I go get a new cat put in soon I'll look for that rattle in the down pipe also, thanks Quote
